BACKGROUND: Peroxisome proliferator-activated receptor (PPAR)-gamma, a member of the nuclear hormone receptor family, which is involved in the differentiation of adipose tissue, is reported to be associated with the pathogenesis of type 2 diabetes mellitus, insulin resistance and atherosclerosis. Whether the prevalence of coronary artery disease (CAD) is associated with Pro12Ala polymorphism in exon B of PPAR-gamma was investigated in Korean adults. METHODS AND RESULTS: The study was conducted in 267 subjects (158 males, 109 females, mean age 58 years) who underwent coronary angiography because of chest pain. Cardiovascular risk factors, such as blood pressure, body mass index (BMI), fasting blood sugar and serum lipid profiles, were assessed in all subjects, who were divided into 4 groups according to the number of stenosed coronary arteries: normal, 1-vessel, 2-vessel and 3-vessel disease. Genotyping of Pro12Ala polymorphism was done with real-time polymerase chain reaction. Allelic frequency for proline was 0.955 and 0.045 for alanine, which was in Hardy-Weinberg equilibrium (p=0.74). One hundred and seventeen subjects (43.8%) had normal coronary arteries, 88 (33%) had 1-vessel disease, 39 (14.6%) had 2-vessel disease and 23 (8.6%) had 3-vessel disease. When the cardiovascular risk factors were compared among the 4 groups, there were no meaningful differences except for age and FBG levels, which were significant even after adjustment for age and BMI. There were no significant differences in the prevalence or severity of CAD according to the different genotypes of Pro12Ala, and in logistic regression analysis Pro12Ala polymorphism was not a predictor for CAD. CONCLUSIONS: There was no significant association between Pro12Ala polymorphism in exon B of PPAR-gamma and prevalence or severity of CAD in Korean adults. Further studies on the correlation between Pro12Ala polymorphism and CAD should be carried out in a larger Korean population in the future.
